Effect of a Catalyst on Reaction Rate: with a lower Ea than for the uncatalyzed reaction. This is shown as the blue path with Ea in the diagram below t a given temperature, a catalyst increases the rate of a reaction by providing a pathway E (RJ) products Reaction Coordinale Since the potential energy barrier is lower in the presence of a catalyst, a greater fraction of the molecules will have sufficient energy to react. Because the reactants and products...

Describe the relationship of activation energy with rate of reaction and the effect a catalyst has on the activation energy. Name two other ways to speed up a reaction besides using a catalyst. 4. 5. Consider the following mechanism for a reaction: No,CNO, + Cl (slow) No,CI+C->NO, +CIh (fast) (a) Write the net reaction and identify any intermediates (b) Derive the rate law for the reaction.

Indicate what a catalyst does in a reaction to change the reaction rate, and provide a possible explanation for how Cu2+ acts as a catalyst in Kinetics of an Iodine Clock Reaction (non-reactive compounds KNO3 and (NH4)2SO4 are added to replace the reactants KI and (NH4)2S2O8) ). Hint: The Cu2+ ion, added in the form of a dilute Cu(NO3)2 solution, makes a suitable catalyst.

A catalyst can not increase the rate of a reaction W. by lowering the activation energy of the reverse reaction X. by lowering the overall activation energy (Eg) of the reaction Y. by changing the value of the frequency factor (A) Z. by providing an alternative pathway with a lower activation energy W.X only All of these are ways that a catalyst might act to increase the rate of the reaction 0 W,X,Y Zonly OX,Z

How does a positive catalyst generally affect a chemical reaction? A catalyst increases the temperature of the reaction which speeds the reaction rate. A catalyst reduces the frequency factor which speeds the reaction rate. A catalyst reduces the amount of solvent required which slows the reaction rate. A catalyst reduces activation energy which speeds the reaction rate.
